2000-15-16: This amendment adopts a new airworthiness directive (AD); applicable to certain Boeing Model 737, 757, 767, and 777 series airplanes; that requires a one-time general visual inspection to determine the vendor and manufacturing date of all oxygen masks in the passenger cabin; and corrective action, if necessary. This amendment is prompted by a report that passengers were unable to activate supplemental oxygen generators during an in-flight decompression due to stress corrosion cracking of the crimped copper alloy ferrules used to secure loops on the lanyard ends. The actions specified by this AD are intended to prevent failure of the supplemental oxygen system to deliver oxygen to the passengers and flight attendants in the event of decompression, which could result in injury to passengers and flight attendants.
2019-09-02: We are superseding Airworthiness Directive (AD) 2018-17-01 for Bell Model 212, 412, 412CF, and 412EP helicopters. AD 2018-17-01 required replacing certain oil and fuel check valves and prohibited installing these valves on any helicopter. This AD retains the requirements of AD 2018-17-01 but expands those requirements for all model helicopters. This AD was prompted by the discovery that we omitted a helicopter model from one of the required actions. We are issuing this AD to address the unsafe condition on these products.
97-15-13 R1: This amendment revises Airworthiness Directive (AD) 97-15-13, which currently requires installing lubrication fittings in the airstair door handle and latch housing mechanisms on certain Raytheon Aircraft Company (Raytheon) Models 1900, 1900C, and 1900D airplanes (formerly referred to as Beech Models 1900, 1900C, and 1900D airplanes). Certain Model 1900C serial number airplanes were incorrectly referenced as Model 1900D airplanes in the Applicability section of AD 97-15-13. This AD maintains the requirements of AD 97-15-13, and corrects the model and serial number reference as described above. The actions specified by this AD are intended to prevent moisture from accumulating and freezing in the airstair door handle and latch housing, which could result in the door freezing shut and passengers not being able to evacuate the airplane in an emergency situation.
2006-21-03: The FAA adopts a new airworthiness directive (AD) for certain Cirrus Design Corporation (CDC) Models SR20 and SR22 airplanes. This AD requires you to check the maintenance records to determine whether the brake caliper piston O-ring seals were replaced at the last annual or 100-hour inspection. If the O-rings were not replaced, this AD requires you to replace the O-ring seals with new seals or replace brake calipers. This AD also requires you to modify the main landing gear wheel fairings to add temperature indicator sticker inspection holes, trim the wheel fairings to prevent them from holding fluids, install temperature indicator stickers on the brake calipers, and insert Revision A6 (with revised preflight walk-around, a limitation on the engine speed used to taxi, and brake inspection/servicing intervals) into the Pilot's Operating Handbook (POH). This AD results from several reports of airplanes experiencing brake fires and two airplanes losing directional control. We areissuing this AD to detect, correct, and prevent overheating damage to the brake caliper piston O-ring seals, which could result in leakage of brake hydraulic fluid. Consequently, this could lead to the loss of braking with loss of airplane directional control or brake fire.
2006-20-02: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 747 airplanes. That AD currently requires inspections to detect disbonding, corrosion, and cracking at the longitudinal rows of fasteners in the bonded skin panels in section 41 of the fuselage, and repair, if necessary. This new AD adds airplanes to the applicability, and requires new inspections of airplanes that may have Alodine-coated rivets installed. This AD results from a report of cracking discovered in a skin lap joint that was previously inspected using the eddy current method. We are issuing this AD to prevent rapid decompression of the airplane due to disbonding and subsequent cracking of the skin panels. \n\n\nDATES: This AD becomes effective November 2, 2006. \n\nThe Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of November 2, 2006. \n\nOn November 27, 1996 (61 FR 57994, November 12, 1996),the Director of the Federal Register approved the incorporation by reference of Boeing Alert Service Bulletin 747-53A2409, dated September 26, 1996.
2019-09-03: We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This AD requires inspecting the jettisoning mechanism of the left-hand (LH) and right-hand (RH) cabin sliding plug doors. This AD is prompted by a report that during a scheduled inspection a cabin door failed to jettison. The actions of this AD are intended to correct an unsafe condition on these products.
95-21-09: This amendment supersedes an existing airworthiness directive (AD), applicable to all Airbus Model A300 series airplanes, that currently requires repetitive inspections for cracking of the No. 2 flap beams, and replacement of the flap beams, if necessary. That AD was prompted by reports of cracking of the No. 2 flap beams. This amendment provides optional modifications for extending certain inspection thresholds, and an optional terminating modification for certain inspections. This amendment also expands the applicability of the existing AD to include Model A300-600 series airplanes. The actions specified by this AD are intended to prevent asymmetry of the flaps due to cracking of the No. 2 flap beams.
